Next, we consider the FitzHugh-Nagumo (FHN) model, which is derived from the works of Hodgkin-Huxley and is famous for its affluence in neuronal dynamics [1]}. Many variations of the original FitzHugh-Nagumo model have been developed since it was first introduced. In the present study, we consider the FHN model given by the following equations [2]}:
\(\begin{split}\dot{v_i} &= \frac{1}{\delta } [v_i(v_i-a)(1-v_i)-w_i]+\lambda _{F}{\sum _{j=1}^N}{A_{ij}}(v_j-v_i)\\\dot{w_i}&=v_i-w_i-b+S(t)\end{split}\)
